Abstract:

This patent discloses that metal halides are ultrapurified by selective complexation with a complexing agent to form a charged first complex. A ligand forms and oppositely charged second complex with metallic impurities in the metal halide to be purified. A solution containing these complexes is then passed through an ion exchange column and the desire purified metal halide collected. The present method is particularly useful in the production of ultrapure metal halides, such as zirconium fluorinate, for metallic glasses. Author tr
